Getting error when trying to convert a pdf file
I added a PDF file to Calibre (it's a comic, so there's a picture on every page), and whenever I try to convert it, it would say "could not convert 1 of 1 books, because no suitable source format was found". The book even displays its first page in Calibre, and it's just PDF which opens fine on my computer, does anyone know why it's giving this error?
